dictate that a mechanical crane cannot or should not be utilized.Materials Covered: Sand, aggregate,

bricks, cement, excavated earth, reinforcement steel (short bars), pipes, and masonry blocks.

 Transportation Modes: Manual head-loads, wheelbarrows, handcarts, tractor-trailers, tippers, or

 Overloading: Vehicles must not be loaded past their legal RTO (Regional Transport Office) carrying

3. Quantitative Constraints (Lead & Lift)

Specifications for conveyance are strictly categorized based on distance (Lead) and vertical elevation (Lift):

 Standard Horizontal Lead: Typically broken down into zones (e.g., initial lead up to 50 meters,

subsequent leads measured in blocks of 50m, or long-range haulage measured per kilometer).

 Standard Vertical Lift: Calculated in increments of 1.5 meters (5 feet) for manual head-loads. Higher

lifts without cranes must utilize secure, engineered scaffolding, ladders, or pedestrian ramps.

other than water retaining Footing for column or foundation (with form work)

As far as possible the preparation of various ingredients of concrete shall be determined on the bases of

preliminary tests as per ISS using the actual materials to be used on site. However in absence of such

preliminary tests the volumetric proportion of 1:2:4 may be adopted i.e. one part of cement, two parts of

coarse aggregates from different stockpiles may be mixed in a suitable proportion to get a uniform mix that

does not segregate.

3.2.4 The coarse aggregate shall not contain dust, clay or other such harmful material. If directed by the

Engineer the same shall be washed with water and dried before being used.

3.3.0 Fine Aggregates:

Fine aggregates shall consist of coarse, angular river sand free dirt and other harmful organic materials. If

directed the same shall be screened and washed before being used. Sand brought from approved source

obtain and store sufficient quantity of water at all times.

3.6.0 Reinforcement Steel:

The reinforcing bars to be provided with CRS Steel & shall confirm to the Tender specifications and relevant

IS specifications. In spite of producing test certificates by Contractor for the proper quality of reinforcing

bars, the quality of steel could also be tested by checking coating firm at plant site for bend test before

doing coating and that if the reinforcing bar fails in bend test, then it shall not be provided with FBEC and in

that case, cost of conveyance of such steel to plant and removing from plant shall be of the Contractors. The

rechecking quality of Steel, for bend test will be done by the coating agency in the presence of contractor

provided the contractor choose to remain present.

Reinforcing bars to be used shall be fresh from rolling rails as far as possible. If the bars are very much

rusted in quality before providing FBEC, such bars shall have a loss of weight at contractor’s risk.

To ascertain the loss in weight of reinforcing bars on account of removal of rust during coating, random

weightment before and after coating shall be done and that loss in weight shall be borne by the contractor.

damages to coating in handling etc. shall be repaired irrespective of their size. This stipulation supersedes

provision of I.S. Code.

3.9.3 No payment will be made for coated bars which are not used in the work and that if they were paid

either on account of coating of the reject able part of bars or doing extra fabrication etc., the amount paid

will be recovered from contractor. The contractor will be paid for the same quantity of steel bars used in the

work and paid under relevant item.

In spite of all test certificates, if the coated bars are roughly handled by contractor either during transport,

fabrication, stacking, placing and concreting etc. or handled in such a manner as to damage the coating for

area or portion more than reasonable, the Engineer-in-Charge or Department/Owner reserve the right to

reject the CRS coated bars and that if rejected then such rejected bars shall be removed by contractor from

work site within three days. The decision of Engineer-in-charge will be final as to reject the bars with

damage coating or to allow repairing the coating, or to get it recoated at contractor’s cost.

Form work shall consist of steel plates or smooth timber planks to be joined by nuts, bolts, nails or pegs so

cleaning of forms shall be done by blasting with a jet of compressed air at no extra cost.

Forms intended for reuse shall be treated with care. Forms that have deteriorated shall not be used. Before

reuse, all forms shall be thoroughly scraped, cleaned, nails removed, holes suitably plugged, joints repaired

and warped lumber replaced to the satisfaction of the Engineer In charge. The Contractor shall equip

himself with enough shuttering to allow for wastage so as to complete the job in time.

used in the structure. It shall be properly anchored to the concrete.

Wire ties passing through beams, columns and walls shall not be allowed. In their place bolts passing

through sleeves shall be used. Formwork spacers left in situ shall not impair the desired appearance or

durability of the structure by causing swelling, rust staining or allowing the passage of moisture.

For liquid retaining structures, sleeves shall not be provided for through bolts nor shall through bolts be

removed if provided. The bolts, in the latter case, shall be cut at 25 mm depth from the surface and the hole

made good by cement mortar of the same proportion as the concrete just after striking the formwork.

The striking time for formwork shall be determined based on the following requirements:

(a) Development of adequate concrete strength;

(b) Permissible deflection at time of striking form work;

Volume-III, Price Bid, Page No.-

(c) Curing procedure employed - its efficiency and effectiveness;

(d) Subsequent surface treatment to be done;

(e) Prevention of thermal cracking at re-entrant angles;

(f) Ambient temperatures; and

(g) Aggressiveness of the environment (unless immediate adequate steps are taken to prevent damage to

Under normal circumstances (generally where temperatures are above 20oC) forms may be struck after

expiry of the time period given in IS: 456 unless approved otherwise by the Engineer In charge. For Portland

Pozzolana/slag cement the stripping time shall be suitably modified as approved by the Engineer In charge.

It is the Contractor's responsibility to ensure that forms are not struck until the concrete has developed

sufficient strength to support itself, does not undergo excessive deformation and resist surface damage and

any stresses arising during the construction period.

machine mixer only. The mix obtained from the mixer shall be a uniform mass consisting of all aggregates

coated with cement paste.

5.2 Fresh concrete shall be transported horizontally in ghamellas or wheel barrows. Vertical transportation

shall be done either by manual labour or using mechanical vertical lifts. When chutes are used for

transportation, care should be exercised to avoid segregation and concrete may be remixed at bottom of

chutes to get uniform mix. Before any concrete is placed in position all loose materials such as dirt, chips of

stones, wood, steel etc. should be removed. Inner side of forms should be coated with thin layer of oil to get

a good finished surface.

Concrete should not be dumped from above in which case aggregate will segregates, but placed gently from

a height not exceeding 1.5 meter. Compaction of concrete shall be done by vibrators till cream appears at

top. Over vibration shall be avoided to avoid segregation.

After concrete is set in position it shall be kept continuously wet with water for 7 days either by using gunny
